Description
Sterilization soluble granula containing kresoxim-methyl and preparation method thereof technical field
The present invention relates to a kind of sterilization soluble granula containing kresoxim-methyl and preparation method thereof, more particularly to a kind of plant protection bactericide of sterilization soluble granula containing kresoxim-methyl and preparation method thereof.Background technology
With the continuous improvement of people's living standard; raising of the people to environmental protection consciousness; and attention of the Chinese government to ecological environment, it is increasing to being adapted to the demand of controlling crop diseases and insect pests and the efficient of No-harmful apple orchard needs, low toxicity, low-residual, free of contamination environment-friendlybiological biological pesticide and chemical pesticide on domestic and international market.
The species of the bactericide of plant protection is a lot, general to use missible oil and wettable powder.It is toxic to human body and plant it is well known that containing a large amount of organic solvents in missible oil, it is easy to volatilize, catch fire, environment is polluted, transport is also inconvenient；Wettable powder can produce a large amount of dust in production, use, pollute environment, influence the health of operating personnel.
Pesticidal preparations develop to solvent free, water baseization, solidification and multifunction direction, and this preparation is based on the sterilization soluble granula of this developing direction development.The content of the invention
The purpose of the present invention is exactly safe and environment-friendly in order to overcome the shortcoming that above-mentioned prior art is present to be used there is provided one kind, and the plant protection containing kresoxim-methyl, which is used, sterilizes soluble granula.
In order to solve the above technical problems, what the present invention was achieved through the following technical solutions：
A kind of sterilization soluble granula containing kresoxim-methyl, is made up of kresoxim-methyl, emulsifying agent, dispersant, wetting agent, binding agent, stabilizer and filler, is counted by 100 % of soluble granule weight, and its composition content is：The % of kresoxim-methyl 2 60, the % of emulsifying agent 1 30, the % of dispersant 1 10, the % of wetting agent 15, the % of binding agent 24, the % of stabilizer 13, remaining be filler.
The emulsifying agent is selected from protective embankment base phenol polyethenoxy ether, such as NPE, OPEO；Ben-zylphenol Polyoxyethyl Ether and the like, such as Ben-zylphenol Polyoxyethyl Ether, benzyl protective embankment base phenol polyethenoxy ether；One or more in biphenyl phenol polyethenoxy ether.
The dispersant is selected from protective embankment base naphthalene sulfonate, such as Nekal BX and pull open powder AC；Double naphthalenesulfonate formaldehyde condensation compounds, such as dispersant N and dispersant N O；And sodium lignin sulfonate.
The wetting agent is selected from one or both of protective embankment base benzene sulfonate, fatty acid amide N- metilsulfates and protective embankment base aryl polyoxyethylene ether sulfate.
The binding agent is selected from one or both of polyvinyl alcohol, beta-schardinger dextrin, methylcellulose and urea.
The one kind of the stabilizer in sodium benzoate, borax, disodium hydrogen phosphate.
The filler is selected from one or both of sodium acid carbonate, anhydrous citric acid, maltose and anhydrous sodium sulfate.
It is a kind of prepare it is above-mentioned containing kresoxim-methyl sterilization soluble granula method, Bao include Yi Xia Walk it is rapid：
1. homogeneous：Kresoxim-methyl active compound and binding agent, wetting agent are mixed in 50 60 °C of water, in 420 450 kilograms per centimeters2Homogeneous is stirred under high pressure；
2. the aforesaid liquid mixture after homogeneous is spray-dried, compound female medicine is made；
3. mediate：After emulsifying agent heat of solution, and dispersant, stabilizer, filler and compound female medicine hot mixing at a temperature of 45 50 °C, then in 46 kilograms per centimeters2Stirred under pressure, mediate uniform, the group's of obtaining agent;
4. extruder grain：Agent will be rolled into a ball in 6 12 kilograms per centimeters2Cylindrical particle is extruded under pressure；5. shaping is sieved after cylindrical particle is dried in vacuo 1 hour under 70 °C.
Kresoxim-methyl (kresoxim-methyl) is a kind of efficient, wide spectrum, new type bactericide.Fungus-caused most of diseases of being cured the disease to Fungi Imperfecti, sac fungus and oomycetes etc. have good preventive effect.Kresoxim-methyl not only has the bactericidal activity of wide spectrum, while with good protection and therapeutic action, being particularly suitable for use in the control of plant disease such as powdery mildew and scab.With other conventional bactericide no interactions resistances, it is and longer than the conventional sterilization agent lasting period.Selectivity with height, it is substantially pollution-free to environment to crop, people and animals and beneficial organism safety.Now it is widely used in vegetables, cereal crop and fruit tree.
It is of the invention to be free of or containing only a small amount of poisonous, inflammable aromatic hydrocarbon solvent compared with existing main flow bactericide formulation, thus the inflammable and explosive phenomenon in production and transporting procedures can be avoided.This formulation does not have unpleasant poisonous smell, excitatory to eyes small, reduces the pollution to environment, substantially increases the security to production, storing and user.Therefore formed after industrialization, not only economic benefit is obvious, and be conducive to promoting the development of high-new environment friendly agricultural technology, be the research direction of sustainable development with obvious social benefit to promoting environmental protection.
Soluble granula is a kind of novel form, is the more comprehensive product of combination property in current pesticidal preparations.Success develop soluble granula Jiang Jin mono- Walk strengthen its to environment, people and animals, crop security.Various raw material sources are all common in domestic Chemical market in formula, and product cost is relatively low, therefore are laid a good foundation for the industrialized production and popularization and application of the formulation.Embodiment
With reference to specific embodiment to Zuo Jin mono- Walk explanations of the present invention.
